Functional Features

The SN74HC164PWR is a high-speed shift register that converts serial data into parallel output. It operates with a clock input and can store up to 8 bits of data. The device features a serial data input (A) and a serial data output (B). The clock input (C) controls the shifting of data through the register. The parallel data outputs (D to K) provide the converted data in parallel format.

Advantages and Disadvantages

Advantages: - High-speed operation - Compact TSSOP-16 package - Wide supply voltage range - Easy integration into digital circuits

Disadvantages: - Limited number of parallel outputs (8 bits) - Requires an external clock signal

Working Principles

The SN74HC164PWR operates based on the principle of serial-to-parallel data conversion. When a clock pulse is applied to the clock input, the device shifts the data stored in the shift register by one bit. The serial data input is sampled at each clock pulse, and the shifted data is available at the parallel output pins. The output enable pin (L) can be used to enable or disable the parallel outputs.

Detailed Application Field Plans

The SN74HC164PWR is widely used in various applications that require serial-to-parallel data conversion. Some common application fields include:

1. LED Display Control: The shift register can be used to control multiple LEDs in a display, allowing for efficient use of microcontroller pins.
2. Data Communication: It can be utilized in serial communication protocols to convert incoming serial data into parallel format for further processing.
3. Digital Counters: The shift register can be employed in digital counters to store and manipulate binary values.

Detailed and Complete Alternative Models

Some alternative models that offer similar functionality to the SN74HC164PWR are:

1. CD74HC164E: This is a DIP-14 package variant of the shift register.
2. 74HCT164N: A CMOS version of the shift register with TTL-compatible inputs.
3. SN74LS164N: A low-power Schottky version of the shift register.

These alternative models can be considered based on specific requirements and compatibility with existing circuit designs.
